The NSK UKT take-up bearing unit is a mounted assembly used to keep chain and belt drives under proper tension. It combines a cast iron fork housing with an insert bearing that has a tapered bore and an adapter sleeve, so it can be fitted onto shafts that are not finish-machined. Typical applications include conveyors, elevators, and other industrial or agricultural machinery where tension adjustment and misalignment compensation are needed.

Reading the UKT code helps you identify the components: UK refers to the insert bearing with tapered bore and sleeve, T to the take-up housing, and the following number to the size. For instance, UKT209D1 uses an insert for a 45 mm shaft, while UKT309D1 matches the same dimensions but belongs to a different bearing series. The D1 suffix marks a design variant of the insert. The matching HA code, such as HA2309, identifies the adapter sleeve, which is tightened with a lock nut and lock washer.

These units are common in belt and chain conveyors, bucket elevators, aggregate belts, food processing machines, bottling lines, and drive systems in milling or feed plants. The take-up housing lets the bearing slide to compensate for chain or belt stretch and to maintain alignment. When selecting a unit, consider shaft diameter, load type, and the operating environment. The tapered bore and HA sleeve simplify mounting and dismounting, and the assembly is secured with a precision lock nut.

Make sure the take-up housing is aligned with the shaft and that the fork allows the required movement. Insert bearing lubrication is permanent in most cases, but in dusty or humid conditions check the sealing and consider versions with additional seals. Always follow the manufacturer's instructions for tightening the sleeve.
